Well, after fixing Gentoo's winedbg wrapper, I got the backtraces you
requested (actually, the whole session, in case it helps). I couldn't tell
if it was the heap code, all of the functions seem to be related to
threading. I eventually ran --debugmsg +all, but still didn't see any
heap-related output. :-/ I attached backtraces of both sessions of winedbg
in case that's where +heap made a difference.
I will try the patch that others suggested and report back on it's effect.
